Case Study: A nurse needs to explain how to use an insulin pen to a newly diagnosed diabetic patient who is anxious and has a low level of health literacy. The best approach is to:

Give the patient the instruction manual and leave them to read it.
Use complex medical terms to ensure the patient understands the science.
Speak slowly, use simple language, demonstrate the process, and then ask the patient to demonstrate it back (teach-back method).
Explain the process once very quickly.
